Hi,
Please see 'Technical Data' tab in a Form View of module you're interested in. You can find this tab by going to 'Settings/Modules/Installed Modules' page and opening any module in a form view. In the tab you'll find some useful information related to your question.
note: if you see in the form view of module only 'Description' and 'Features' tabs, then you'll need activate 'Technical Features' access right for your user. For do that, go to 'Settings/Users/Users' page, open there your user, edit it and check 'Technical Features' checkbox in a 'Access Rights' tab. then log out and log in again to openerp.
regards,
this question is the same as my question https://www.odoo.com/nl_NL/forum/help-1/question/how-to-get-modules-dependencies-85588 but it was phrased in more better way than mine so it got more valuable replies
